I've got a pretty much stock LS1 (with LS6 intake), power steering, EVAP, AIR, air-con removed. I don't know a huge amount about these engines but I've picked up that the LS1 (mine was from a Firebird Trans-Am) was de-tuned. What kind of power can I expect to get out of this engine unmodified and how much power can I make it produce without replacing anything (i.e. with LS1Edit for example)?

 

might want to post this in the PCM Diagnostics and Tuning section instead of here.

 

OK, will do... thanks
